Radius variable cleaning paw

Abstract

Disclosed is a changeable radius cleaning grip, belonging to the art of mechanical arm. The invented contains: a right brush arm, a left brush arm, hair brushes, an on-off device and a facing bar, the root of the right brush arm and left brush arm symmetrically being hinged to the facing bar, and the heads of the right brush arm and left brush arm locating separately at two levels, non interfering to each other, and the heads of the right brush arm and left brush arm wrapping the insulator by cross; a plural of hair brushes being separately equipped with the upper-side of the right brush arm and the lower-side of the left brush arm; and the on-off device being fastened on the facing bar and hinged separately to the roots of the right brush arm and left brush arm to accomplish the on-off movement. With a changeable bend radius of right brush arm and left brush arm, the ground device does not need to move in the whole process of cleaning the conical insulator, it being safe and reliable.

Description

technical field [0001] The invention relates to a device in the field of mechanical technology, in particular to a cleaning claw with variable radius. Background technique [0002] The pollution flashover of the insulator seriously endangers the safe operation of the power system. Cleaning the outer surface of the insulator in time is an effective measure to prevent flashover accidents without affecting the normal operation of the power grid. For live cleaning equipment for substation insulators, the performance of the end effector directly affects the cleaning effect. In addition, there are various shapes of insulators in substations. Designing cleaning tools that can well adapt to these shapes, especially conical insulators, is an important requirement for new insulator cleaning equipment. [0003] Through literature search to prior art, it is found that the patents and technologies related to substation insulator live-cleaning equipment include: the publication number i...

AI Technical Summary

Problems solved by technology

The publication number is CN1065819A, the patent name is a pneumatic wind wheel ultra-high voltage live cleaning device, and the application date is April 16, 1991. The patent describes a hand-held live cleaning brush, which is driven by a wind wheel. The handheld tool is located on the ground. This device can be used for cleaning conical insulators, but requires the operator to move the position repeatedly to clean the surrounding area of ​​the insulator.

In addition, Yu Huayu and others published the "CZQ-50 Ultra-high Voltage Live Automatic Cleaning Machine" published in "China Electric Power" (2001, Vol. 35, No. 1) p77-79. The diameter of the brush disc can be automatically adjusted within a certain range, but when cleaning the large radius part of the conical insulator, the claws cannot be completely surrounded, so the ground equipment still needs to move the position repeatedly to clean completely
